SEWING-MACHINE.

Be it known that I, Momus M. SOIiiRAGO, a citizen'of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented new and useful Improvements in SewingMa-j chines, of which the following is a specifica tion.

This invention relates to improvements in sewing machines, and more particularly to the seaming together of materials where fullness is necessary on the top seam.

It has for its object to provide a new and simple and effective means whereby the seaming up of any garment, belting, leather, rubber, canvas, goods, as well as other miscellaneous materials where fullness on the top seam is required. i v

In practising my invention Iprovide a presser footand a ribbon or strip, one side of said ribbon or strip having spaced serrations thereon. This strip has its smooth face adjacent to the under side of-the presserfl foot and the width of said strip is usually equal to the width of the presser foot'toe.

If it is desired to seam any garment in which fullness is necessary on the top scam," .the garmentls placed on the sewing machine in the usual; position necessary for sewing and the strip is extendedso as to lie upon the garment,after which the presser foot is released by lever means into operative position. The serrated surface of the strip then bears on the top surface of-the material. In this case by pushing said material towardthe presser foot the top cloth would become corrugated or have a full appearance,while the undercloth to which the top clothis to be sewed would remain flat. It will be understood that as the needle mechanism .commences its work the stitches will follow along the edge of said strip, and the presser Specification of Letters Patent.

sleeve head is Toasted. The garmentis then seamed and pressed until the fullness ois removed so that the goods lie as straight as the piece to which it was basted. When this is accomplished the garment is then sewed.

However, my invention overcomes all this unnecessary labor, saving time andthread.

PatenteolDec. e, 1921.

With my invention it is possible to seam up any garment where fullness is necessary on the top seam directly on the sewing machine without any basting, seaming, etc.

In addition it is most difhcult. for, anybut the most expert manipulator of sewingmachines to sew a perfectly straight seam espe .cially in sleeve heads or around the bottom of ladies" dresses, as above-mentionedfbut I with my invention it is perfectly possi'ble'to overcome this difiicu'lty and sew a straight seam, inasmuch as the edge of the strip acts as a guide for the operator as well as holding the goods in place when said goods is resting on'the top frame of the sewingmachine. By using my invention themost in experienced person may after a few weeks practice become more expert than would an all-around operator with years of experience be able to accomplish, by the old method of obtaining fullness on the top seam.

With the above and other objects in view, my invention consists in novel and useful provision, formation, construction, combination, association and inter-relation of parts, members and features, all as disclosed inthe accompanying drawing, described in the specification and finally defined-in claims.

' In the drawingi Figure 1 is an end view of a sewing machine head with my improvement connected thereto v i s Fig. 2 is a fragmentary isometric view of my improved sewing machine member showinga presser foot with container member for holding a strip asw'ell as means joining said container and presser foot; I V

Fig. 3 is a cross sectional view of the container member;

.Fig. 4 is an isometric view of the presser foot and means ]O1111I1g sald presser foot and container member, said means being shown :as fragmentary;

Fig. 5" is a fragmentary isometric view showing the serrated surface of the strip; and it 1 Fig. 6 is a side view of the strip showing the serrations thereon.

Corresponding parts in all the figures are designated by the same reference characters.

Referring with particularity to the draw ing, A designates a sewing machine head" with its usual attendant features as a presser bar 1, a needle bar 2, presser foot thumb screw 3, and needle 4. B designates the bed of a sewing machine with a feed dog 5 projecting therethrongh. C designates my improved means comprising a presserfoot a, a strip 5, a container member or casing c for holding the strip or ribbon b and a member. cl joining said container member v0 and the presser foot a. The presser foot a corre sponds in design to any presser foot used on and made for any make of sewing machines. The presser foot a is attached to the presser bar 1 by the presser foot thumb screw 3 in the usual manner. The member dis fastened to the presser foot as as at 6 and forms an integral part with said presser foot a.

In the showlng the presser foot a and the member 03 have a web member '7 between them to maintain rigidity.

The member d is channeled as at 8, said member (Z having a plane upper surface 9, sides lOand 11 and spaced bottom members 12 and 13 parallel with said top member. By referring to Fig. 4 it will be observed that the channeled portion of the member d connecting the presser foot (45 has its side members 12 and 13 in spaced relation to the foot of said presser foot as at c. This is in order to allow the strip member I) to pass from within said channeled portion 8 and down under the toe. of the presser foot or as illustrated in Fig. 1. The member a? is connected to the presser foot 0: and is of such a width that the strip 6 is guided at and under the toe 14E of the presser foot 0, so that the edge of the strip 6 ,is even with the edge of the presser foot a, as at 15, that is, the edge next to the needle 4.

The strip 6 is provided at itsffree end with a clip 7, and the clip f is bent upward at its end as at17 and is for the express purpose of hooking to the bent up portion of the toe of the presser foot member a as at 18 and in addition prevents the strip 1) from being drawn into the channeled portion of the member 03. The opposite end of the member at is connected to the member cand the member 0 is provided with a slot which joins with the channeled portion8 of the member d. The casing or container member 0 is provided with a partition 9, which partition g divides the casing or container 0 into two parts- One of saidparts as 71, holds the strip Z) while the other section 7' holds a spiral spring or tension means y. The partition g isheld to the inner surface of the member 0 in any approved manner. A rod 19 extends through and at a median section of the partition g. This rod is provided 'with collars 20 and 21. The collar 20 is provided with threaded perforations 22 and joins with spaced recesses 23 in the rod 19; thus by insertinga screw in the perforations 22 the collar 20 may be rotated and locked into any position desired for the purposes about to be stated. Thecollar 21 is likewise either permanently or adjustably connected to therod 19. The spiral spring 1 has one end connected by suitable means to the inner surface of the member a and on the side designated as 3', while the opposite end is connected to the collar 20. The opposite end of the strip, that is, the end that is farthest removed from the clip is connected to the collar 21, and thus when the strip is wound upon the collar 21 the tension with which it is drawn into or out of the container 0 may be regulated by adjustin the collar 20 which connects with the spira spring. The container c is provided with covers or capsk/ These caps 70 have at their median section as 2 1, a bearing, said bearing accommodating the ends ofthe rod 19, and which, in conjunction with the member 9 supports the rod 19 so that samemay rotate as the strip 6 isflmoved inwardly or outwardly of the". container 0. The member 0 is likewise sup plied with slots 25, said slots having two right-angled portions. The caps is are provided with small pins 26 extending radially downwardly, and it is intended that the pins should engage the slotsfi25'so that the caps 7 is may be locked in placeupon the container 0.

While Ihave hereinbefore specifically described my invention and its several fea'-' tures with reference to the particular em bodiments' thereof which are illustrated in the drawing, it will be understood that the invention in principle is equally applicable to any style of machine in whichfsewing is accomplished; and further, that it may be variously modified in its various details within the scope of the appended claims,

without departing from the spirit or sacrificing the advantages thereof.

Havln thus disclosed my. inventiom l claim an desire to secure by Letters Patent;
